Hi Grant,
Hmmm, I hadn't thought about this. I was intending to use the
Virtex's memory region for all virtio, but if I can allocate memory
regions on both sides of the PCI bus, then that may be best.
Sounds like you can experiment and see what works best :)
If you use
a PCI Target only cor

Hi Grant,
Thanks David. I haven't looked closely at the xilinx pci data sheet
yet, but I don't expect too many issues in this area. As you say, it
won't take much to code it up. I'll be poking my VHDL engineer to
make it do what I want it to. :-)
The key aspects of the core will be that it
Hi Grant,
I like this a lot. I need to do much the same thing on one of my
platforms, so I'm going to use your patch as my starting point. Have
you made many changes since you posted this version of your patch?
I'd like to collaborate on the development and help to get it
mainlined.
In my cas
